Science fiction writer Isaac Asimov came up with three laws of robotics: a robot may not harm a human, a robot must obey humans and a robot must protect its own existence.

The Washington State Senate thinks even more regulating laws are necessary. On Wednesday senators voted unanimously to outlaw ticket bot computer software that buys up to 40 percent of the tickets for a concert before the public gets a stab at them. This is only the latest effort to regulate robots and robotic software.
